T304 Stainless Steel, High-Pitch X-Pipe, Vacuum Valve Control
Overview
Transform your supercharged V6 into a true auditory experience.
Our Valvetronic Designs Valved Exhaust System for the Audi B8 and B8.5 S4/S5 delivers a unique, high-pitch wail while retaining low-end rawness for a sound profile unlike anything the platform has heard before.
